Análise de verificação da infraestrutura e da segurança viária do brt norte-sul de goiânia: diagnóstico e propostas de melhoria. Estudo de caso

Abstract

This study presents a technical analysis of the infrastructure and road safety conditions of the North-South BRT corridor, located in the city of Goiânia, Goiás, with emphasis on the segment between the Paulo Garcia and Hailé Pinheiro terminals, covering the Jenipapo, Jatobá, Jacarandá, and Praça do Violeiro stations. In an urban context marked by the growth of the vehicle fleet, intensified travel demand, and greater exposure of vulnerable road users, the study highlights the importance of high-capacity public transport systems, such as Bus Rapid Transit (BRT), in promoting safer, more efficient, and more sustainable urban mobility. However, the performance of these systems depends directly on the adequacy of the infrastructure, universal accessibility, and compliance with road safety principles.The research is descriptive in nature and adopts a qualitative and quantitative methodological approach, structured as a case study. The method is based on the application of the Road Safety Audit (RSA), used as a preventive tool to identify deficiencies associated with geometric design, operation, and maintenance of road infrastructure. Initially, a literature review was conducted using books, scientific articles, legislation, and technical manuals related to road safety, urban mobility, and BRT systems, in order to provide the theoretical basis for the analyses developed. Additionally, documentary analysis was carried out using urban mobility plans, system operational data, institutional records, and official traffic crash statistics. The fieldwork stage included technical visits technical the corridor, with visual inspections, systematic observation, photographic records, measurements, and the application of technical checklists based on RSA protocols. These tools made it possible to assess elements such as road geometry, pavement conditions, horizontal and vertical signage, public lighting, accessibility, pedestrian crossings, urban furniture, modal integration, and the operational conditions of the stations.The collected data were processed through descriptive statistical analysis and qualitative content analysis, enabling the identification of patterns, critical points, and nonconformities in relation to national and international technical standards and guidelines. The results indicate the presence of deficiencies, including deteriorated sidewalks, failures in tactile paving, poorly located crossings, worn horizontal signage, insufficient lighting, architectural barriers, and the absence of suitable areas for taxi and ride-hailing pick-up and drop-off. Such nonconformities compromise universal accessibility, increase exposure to risk, and reduce the operational efficiency of the system.As a contribution, the study proposes corrective and preventive technical recommendations, prioritizing low-cost, high-impact interventions aimed at improving road safety, accessibility, and the quality of urban public transport.Keywords: Public transport.
